    Abstract:
    BACKGROUND & AIMS: The majority of patients with familial adenomatous polyposis (FAP) develop duodenal adenomas with a risk of progression to duodenal cancer. Endoscopic management of FAP duodenal adenomas has been proposed as a less-invasive option than surgery, but available data still are limited. Our aims were to assess the feasibility and safety of endoscopic treatment in duodenal polyposis and to evaluate its long-term efficacy in terms of recurrence and malignant degeneration. METHODS: FAP patients with stage IV duodenal polyposis were enrolled in 5 French centers as part of a national cohort and followed up for a median period of 5.66 years (interquartile range, 6.39 y). Primary outcomes were duodenal surgery-free and cancer-free survival. Two groups of patients were identified according to endoscopic procedures: group 1: resection and or destruction (by argon plasma coagulation) of duodenal polyps, and group 2: papillectomy. RESULTS: Fifty-eight patients were enrolled (29 men; median age, 44 y). Endoscopic therapy was performed in 37 patients in group 1 and in 19 patients in group 2. Duodenal cancer-free and surgery-free survival were 95.8% at 5 years and 92.6% at 10 years. Four patients required surgery and 2 patients developed cancers. In the 58 patients, the calculated Spigelman score decreased from 9.24 points at entry to 6.35 at 5 years and then plateaued. Complications (mostly bleeding and perforation) occurred in 20 patients. CONCLUSIONS: In this long-term cohort follow-up evaluation, endoscopic treatment of patients with severe duodenal polyposis appears relatively safe and effective as an alternative to surgery for the prevention of cancer.
